Molybdenum Wire For Edm

Product Introduction

The Molybdenum Wire For Edm supplied by Shaanxi Chuanghui Daye Metal Material Co., Ltd. is a high-purity molybdenum product designed specifically for Electrical Discharge Machining (EDM) applications. Manufactured with advanced drawing and annealing processes, this wire offers outstanding mechanical strength, excellent electrical conductivity, and exceptional resistance to high-temperature oxidation.

With more than 30 years of expertise in rare metal production, our company ensures that every molybdenum wire meets strict international standards such as ASTM B387 and GB/T 4182. The product is available in various diameters and spool sizes, offering consistent performance in high-precision cutting of conductive materials like steel, copper, and tungsten carbide. It ensures stable discharge, high cutting accuracy, and extended operational life for all EDM machines.

Molybdenum wire has high strength, high melting point, corrosion resistance, and wear resistance. Specifically, molybdenum wire in online cutting processing exhibits characteristics such as high strength, good discharge performance, high surface smoothness, fast cutting speed, and long service life. In addition, molybdenum wire also has good conductivity and is commonly used as the filament and lead wire of light bulbs.

Manufacturing & Process Flow

Our Molybdenum Wire For Edm is produced using advanced metallurgical techniques and controlled environments to guarantee purity, strength, and consistency:

1. Raw Material Selection: High-purity molybdenum powder (≥99.95%) is sourced and inspected to ensure chemical stability.
2. Powder Pressing: The powder is compacted under isostatic pressure to achieve uniform density.
3. Vacuum Sintering: High-temperature sintering in a vacuum furnace enhances grain structure and mechanical strength.
4. Hot and Cold Drawing: Multiple precision drawing steps refine wire diameter and improve surface finish.
5. Annealing Treatment: Controlled thermal processing relieves stress and enhances ductility.
6. Surface Cleaning: Electrochemical and chemical polishing ensure a bright, oxidation-free finish.
7. Spooling and Packaging: The wire is wound on spools under controlled tension for smooth and consistent unwinding.

Each stage is monitored by experienced technicians to ensure dimensional precision, surface integrity, and mechanical performance.
